The Lateral root of the median nerve (Mn) had two parts. The distal part of the lateral root (dLr) was arising from the lateral cord (Lcd) of the brachial plexus medial to pectoralis minor muscle (Pm) and winds round the axillary artery (Aa) before joining the lateral cord again. The proximal part of the lateral root (pLr) was arising from lateral cord lateral to pectoralis minor muscle and joins the medial root (Mr) of median nerve. The medial root of median nerve (Mn) was arising from medial cord (Mcd) and then winds round the axillary vein (Av) before joining the lateral root to form median nerve. Mc- Musculocutaneous nerve.
